Abstract

a invenção se refere a uma unidade de filtração (1) destinada a permitir a desleucocitação do sangue ou de um componente sanguíneo, que compreende um invólucro exterior (2) dotado de pelo menos um orifício de entrada (3) e de pelo menos um orifício de saída (4), em que o invólucro encerra um elemento poroso interposto entre os ditos orifícios, em que o dito elemento poroso encerra pelo menos um pré-filtro (7) para eliminar os agregados e pelo menos um meio de desleucocitação (8) por adsorção e/ou por filtração dos leucócitos, em que o pré-filtro (7) para eliminar os agregados compreende pelo menos um véu não tecido coerente que compreende uma mistura de primeiras fibras termoplásticas e descontínuas e de segundas fibras termoplásticas e descontínuas em que um ponto de fusão é inferior àquele das ditas primeiras fibras, em que as ditas primeiras e segundas fibras são ligadas por uniões térmicas entre si.
